Vim Jump-Start

Filed under: Linux — Nasser Heidari @ 20:11

Thanks goes to roqet

vi (and vim) runs in 2 modes: insert and command, ESC changes to command mode.

This command list was made while using vim (vi improved), all commands may not work in other versions of vi.

In this document, c stands for ctrl and m for alt.

% usually represents the whole buffer

If you’re having trouble starting vim in a console, try vim -X

See the “additions to the vimrc configuration file” section to enable ms-windows-like editor commands.

basic commands

quit : :q (closes the editor, use :bd to just close the buffer)

write/save : :w

quit with write : :wq

quit without save : :q!

close buffer : :bd

open file : :e (filename)

new file : :new

page up : c-u or page-up

page down : c-d or page-down

up : k or up-arrow

down : j or down-arrow

left : h or left-arrow

right : l or right-arrow

go to file start : gg

go to file end : G

go to line : nG (where n = a number)

go to line end : $

go to line start : 0

jump forward word : w

jump forward word : b

begin typing/insert : i

insert at end of line : A

join lines : J (nJ to join more than 2 lines – n = a number)

indent a block : v (then select the block) > (or < to go left)

undo last command : u

redo : c-r

repeat last command : :<up arrow>

repeat last change : .

select : v (then select text, and choose y to copy or x to cut)

copy line : cc

delete line : dd

delete character : x

delete word : dw

delete till end of line : d$

delete several lines : :dn eg :d3

delete a specific line : :nd (where n = a number, not to be confused with above)

paste (after character/line) : p

paste (before character/line) : P

search forwards : / (followed by word to search) (/ alone to search next)

search backwards : ? (followed by word to search) (? alone to search next)

search files : :vimgrep /love/ *.txt follow this with the command :cwindow to see a list of all the files found

change case : n~ (where n = a number)

replace/substitute : :%s/old/new/g (% says to do this for each line, % can also be a set number)

replace single character : r<character>

match parenthesis : % (after placing the cursor on the first parenthesis)

code complete : ctrl-x ctrl-o

word wrap : :set wrap

no word wrap : :set nowrap

line numbering : :set number

no line numbering : :set nonumber

execute an external command : :! (followed by command)

read in results of a command : :r!command or !!command (eg :r!date)

insert an external file : :r (filename)

open a shell : :sh

create a page break : while in the insert mode, CTRL-l (that’s an “L”); “^L” will appear in your text and will cause the printer to start a new page.

execute perl : :!perl -wc % (for syntax check, drop the “c” for normal run)

compile java : :!javac -verbose %

run java : :!java %< (the < removes the extension)

compile c#: :!csc %

spell check : :!ispell % (or :!aspell check %)

new buffer : :new

next buffer : :bn

last buffer : :bl

change buffers : :(n)b

close buffer : :bd (close specific buffer = :bd 3 (can have more by putting a space between the numbers))

change between split windows : c-w

make current window the only one visible : :only (or) c-w o

change/set options : :options (these can also be set in the .vimrc/.gvimrc

files)

create/run a macro : qa to begin recording into register ‘a‘, followed by q to stop recording, then @a to repeat the commands you recorded. You can record into 26 other registers (for each letter of the alphabet).

create a fold : zfap (position the cursor at the start of the block of code first)

open a fold : zo

close a fold : zc

open all the folds : zr

close all the folds : zm

Make current line uppercase : gUU

Make current line lowercase : guu

htmlize a syntax-highlighted file : :runtime! syntax/2html.vim this will convert a file that has been syntax highlighted into html (handy for use on websites and such)

additions to the .vimrc configuration file

additions to syntax highlighting

These are my preferred additions to the $VIM/filetype.vim file:

" Delphi forms
au BufNewFile,BufRead *.dfm			setf pascal
" ChangeLog addendum
au BufNewFile,BufRead *.changelog		setf changelog
" useful if you use vim to read your SQL*Plus buffer (afiedt.buf)
au BufNewFile,BufRead *.buf 			setf plsql
